CX9SM AT CRYSTAL
14 MHz to 250 MHz
Low Profile,
Ultra-Miniature
Surface Mount AT Quartz Crystal
DESCRIPTION
Designed and manufactured in the USA, Statek’s CX9SM
AT quartz crystal is the newest device available in frequencies
ranging from 14 MHz to 250 MHz. This device has been
specifically designed for applications requiring a very small
foot print and low profile. It is 4.1 mm x 1.5 mm with a height
under 1 mm. Using micro-machining processes, this surface-
mountable crystal is hermetically sealed within an ultra-
miniature ceramic package to ensure high stability and low
aging. Tight calibration and excellent frequency/temperature
stability make the CX9SM ideally suited for many high
frequency applications.
